The Negative Sideburn (also known as "negburn") is achieved when one elects to shave their sideburns above the ear line.

Although various execution methods exist, negburns are best visualized by imagining someone putting on a pair of glasses, then lopping off all hair beneath the ear piece.

When your barber, seemingly obsessed with sideburn symmetry, screws up so badly that your sideburns embarrassingly begin ABOVE your ears.
